Bird, who’s just 23 years old played in 13 games for the Celtics last season, averaging three points and 1.5 rebounds per game. He was a second-round pick in the 2017 NBA Draft out of California, where he averaged 14.3 points and 4.7 rebounds per game during his senior season.

He is a restricted free agent, which means the Celtics would be able to match any offer an opposing team makes to him.
